ELASTIC 'WHEEL Application filed March 18. 1916.

To f/ frito/11 if 11ml/ concor/i:

lie ilr known that l, Joint Snaiwna. a citizen ol the llnited States, residing at lrving, in, the county of Tania and State o'l lowa, have invented certain new and useful linpri'iienienls in YElastic lVheels; and l do hereby declare the following to he a il'ull, clear. and exact description ot' the invention. such as will enable others skilled in the art to which il' ainierl'aius to make and use the saine.

This invention relates to vehicle wheels, more especially those, used on automobiles and motor trucks; and the object oil? the invention is to produce an elastic wheel7 independently oi" the tire, whereby the desired resiliency may be obtained without depending entirely on the tire.

The, invention consists lin a novel construction ot the wheel whereby the l'elly and iir are held in proper yrelation to the hub by suspending and supporting springs adapted to give `universal limited movementwith suitable, provision ior the exclusion of niud and dust from the working parts.

ln the accom partying drawing, lforinii'ig a part o" this specification, Figure l is a side elevation oit a wheel embodying` my inven- Ixionv` with one side removed to show the internal construction. Fig. 2 :is a central crossseclion of the saine. Fig. 3 is an enlarged, partly sectional view o'l a pair ot the spring hangers.

in the i'lrawing, the numeral l denotes the axle ot the vehicle, on the spindle oit which is nuuinted the hub oit the wheel by ballheariugs In practice the hub is composed ot two or more parts, .5 and ai, screwed together as shown. The former is in the nature ot ay spider 5, its arms serving as bearings for the spring lnuigers (S and 7. These have bosses4 8 liournaled in the spider-arms and the eyes 9 oi: the springs l()7 and are connected in pairs by suitable screws l1. .ris the hangers cross, one pair is otlset at l2 so as to play inside the other pair. lThe springs are suitably clipped to the riin or l'elly of the wheel 13, which consists essentially ot a pair oi similar disks having rightangled annular flanges lsl. abutting' when in operative position, one ot' the flanges being provided with an internal ring llla adapted to telescope into the companion hange, as clearly shown at the bottom of Fig. 2. Central to each disk is a hole 17 large enough Specification of Letters Patent.

to allow for all necessary movement ot' the wheel hub in any direction. The main disks are suila bly fastened together, as by bolts 18. Outside the main disks, and held in place by the hub(` is a pair of concave covering disks 19 adapted to cover the holes in the niain disks at all times, and to exclude mud and dust from the interior.

The springs are semi-circular in forni, and designed for both suspension and compression. The attachnlent of the ends of the springs is also such as to counteract, llexibly, the torsion of the hub, as is necessary when the wheel is used as a driver. The action of the springs is thus practically universal and secures substantial uniformity ot' tension in all its working directions, and whenever a liolting stress is applied to any point on the periphery of the Wheel.

lt will be noted that the hangers are attaehed to the middle leaves of the springs, the outer lea ves being held in proper operative position by stirrups Q0 slidable slightly on the middle leaves.

The construction is such as to give convenient access to the interior oi the wheel, for inspection or repairs, and to facilitate the attachment oi new tires and the reino al ot old ones. The interior of the wheel may be inspected. without even jacking up the wheelj by merely unscrewing the outer haltl ot the hub, which holds the dust-excluding disk in place, and unbolting the two halves ot' the wheel. The outer half may then be removed, without disturbing the half attached to the axle. To remove the tire it is oi course necessary to jack up the wheel.

Having thus described my invention7 I claim:

l. An elastic wheel, comprising a pair of disks having inturned, annular flanges oi. equal diameter, one disk having an internal ring projecting laterally beyond its flange, and adapted to telescope inside the flange ot the companion disk, suspending springs attached to the disk having Said internal ring, and a hub-spider with arms linked to the ends of said springs.

2. rin elastic wheel, comprising a pair ot disks with large central holes and abutting annular flange, one of said disks having an attached internal ring projecting laterally beyond the flange, and adapted to telescope inside the flange of the companion disk, suspension springs attached to the disk having lfu ln testimony whereof I aflix my signature in presence of two Witnesses.
